v The present invention relates to a coin-box for telephone instruments, especially for a telephone station connected to an automatic exchange. The present coin-box is to serve as an auxiliary apparatus for a telephone instrument of the usual construction; its main feature is its particularly simple construction.

The advantage of the simple construction is achieved according to the invention by using a coin-box that is accessible to the subscriber while paying-in and receiving-back the coins, that can be rotated into various positions by means of an operating handle and that in accordancewith its positioning actuates contacts that enforce the proper use of the coin-box.

Special coin ducts, which increase the cost of the coin box, are avoided by using a coin container, which can be rotated about an axis and can be so rotated into the coin receiving position that the subscriber can directly insert in and remove from the container the coins. A cheap construction of the coin-box is rendered possible mainly by not having a special giving-back device. Since no coin ducts are used in the present coin-box, it is necessary to use a method of testing that difiers from that hitherto used.

According to the invention the testing of the coins for their maximum diameter is done with the aid of a stop extending into the path of the coins. Testing the minimum diameter of the coins is efiected with the aid of a feeling lever, by means of which contacts are actuated. After setting up the connection, it must be possible for the subscr ber to remove from the apparatus the inserted C01IlS when he wrong subscriber answers the call, there-.

fore it is necessary to ensure that the estab lished connection is destroyed when the subscriber makes use of this possibility.

According to the invention this is ensured by a contact, that interrupts the exchange loop in the coin-receiving and giving-back positions of the coin-box. Only when the coin-box is rotated into the selecting position, is this contact closed. The time required to ensure the release of the connection when the money is to-be returned is not determined as hitherto by a clockwork, but by an involved manipulation due to the design of the apparatus. It is namely necessary ior'the subscriber to bring the coin container to the coin-returning position from the position in which he could set up the connection, and only then can he remove the coin from the con tainer. The time taken to do this is so great that the switches'in the exchange have had plenty of time to release.

One method of carrying out the invention will now be described.

Fig. 1 shows the circuit 01"" the coin box in conjunction with a telephone instrument. Fig.2 shows diagrammatically the mechanism of the coin box. Fig. 3 is a'longitudinal section through the coin box.

It can be seen from the 1 that there is no mechanical connection whatever between the coin box and the telephone instrument. There are merely a. few connecting leads between the coin box and the telephone instrument, they go to the contacts I, ll and-III of the coin box. The circuit of the telephone instrument is that of a standard subscribers instrument. Obviously the invention can also be applied to other types of substation circuits.

The designations shown in the circuit have the following meaning: use is the impulse contact located at the number dial. EU is a switchhook contact; M is the transmitter, F is the receiver, VVi 1 and Wi 2 are resistances. "W designates the calling bell. In the circuit the contacts I, II and III are shown in the position, in which the'coin box is in the coin receiving and giving back position. This position of the coin-container is designated by A in the Fig. 2. In theposition B (Fig. 2) of the coin-container the contacts I and III are closed, provided that thereis acoin in the coin-container, and contact 11 is open. In the coin-containers position C (speaking position) the contacts 1' and H are closed and the contact HT is open. y

When a call is made to the t lephone station, the coin container 2 must be rotated into the speaking position C by means ofthe handle 1 (Fi After taking down the receiver, the subscribers instrument is then ready for speaking.

To make a call in the outgoing direction, the coin container 2 must first be rotated into the receiving position A and the required fee inserted into the coin container. In this position the exchange loop is interrupted by the contact I, so the coin container 2 must then be rotated into the position B. The contacts II and III are switched-over by means of the coin feeling lever 3. With his number dial the subscriber can now position the switches, because the contact II has removed the short circuit from the impulse contact mi. But the transmitter is short circuited by the contact III. When the right subscriber answers, the coin container 2 must be rotated into the position C in order to remove the short circuit from the transmitter M. The coins 4 in the coin container 2 then drop into the cash box 5. If the connection be not established, the coin-container 2 must be rotated back from the position B to the position A and the subscriber can then remove the inserted coins. But in position A the contact I is opened, thus destroying the established connection.

.The construction of the coin-box will now be further described with reference to the Figs. 2 and 3. The coin container 2 is fixed to the shaft 6, which is supported at the points 8 and 9 in the casing 7. The shaft 6 is rigidly connected to the operating handle 1. The coin container 2 is subdivided into a number of coin chambers 10, so that several coins can be inserted into the container 2. The coin chambers 10 are formed by plates 11 that are held together by two rivets 12 and 13 and the gaps between them are determined by the distance pieces l4.f The maximum diameter of the coins is determined by the distance of the edge 15 from contact surface where the part 14 touches the coin 4:, hence the parts 14 are exactly calibrated. On the shaft 6 there is also rotatably mounted a part 16 carrying a cover plate 17 that covers the coin slot when the coin container is in the positions B and C. By means of a coupling spring 26 the part 16, which can rotate about the shaft'6, is moved in the direction of the arrow when the coin container 2 is 1'0- tated into the positions B and C. i The part 16 has an engaging piece 18, which is pressed against the coin container 2 by the action of the spring 26. The rotatable part 16 is not moved beyond the pin 19 when the coin container 2 is rotated into the position C. The end of the cover plate 17 is so bent that its end portion operates the contact I when the coin container 2 is in the positions B or C. The upper part of the casing 7 has a cast body 20 with a slot for the insertion and withdrawal of thecoins. Feeling levers 3 project into the path of the coins 4; these levers can rotate about the axis 21 and are under the action of the spring 22. When a coin of sufficient diameter is inserted into the coin-container 2 and the latter is in the position B, the contacts III and II are switchedover by the feeling lever 3. As already mentioned, the coin-container 2 has a plurality of coin chambers, into each of which projects a feeling pin 3. The construction can be such that the contacts II and III are operated only when every feeling pin 3 is moved by a corresponding coin. It is possible to provide as many contacts II as there are feeling pins and to contact these contacts in parallel. Thereby is achieved that the short circuit is removed from the impulse contact only when the required number of coins are in the instrument. The coins 4 fall into the cash box 5 when the coin container 2 is rotated from the-position B into the position C. To prevent fraud due to the coins being stuck or jammed tight in the coin container so that they cannot drop out in the position C, sliding-out pieces 23 are fitted that project into the coin chambers like fingers and press-out the coins when the coin container is rotated into the position C. In order to mark the positions A, B, and C for the coin-container, a spring 24: is fixed to the casing 7 and it lies on the square-shaped part of the shaft 6.
